HEEL-BURNISHING MACHINE.

SPEQIFICATION forming part of Letters Patent No. 466,258, dated-December 29,1891.

Application filed October 9, 1890.

To all whom it may concern:\

' Beitknown thatLEvERETTRRIOHARDsON, of Lawrence, county of Essex, Stateof Massachusetts, have invented an Improvement in Heel-Burnishing Machines, of which the following description, in connection with the accompanying drawings, is a specification, like letters on thedrawings representing like parts.

My invention relating to heel-burnishing machines is embodied in a machine in which the burnishing-tool and its adjusting mechanism are of the construction found in the well-known Tapley heel-burnishing machines, shown in patent to Hawkins, Meade, and Spear, No. 113,658, dated April 11, 1871, and in many later patents.

In my machine I use novel means for moving the jack and boot or shoe held therein in and out with relation to the burnishing-tool in the direction at right angles to the stroke of. the tool and also for giving the heel the requisite rising and falling'movement during its in-and-out movement. These means consist in pivoting the jack-support in a certain relation to the tool, so as to cause the risingand-falling movement of the heel when the said support is swung in and out on its pivot, and also in connecting mechanism between the frame-work of the machine and the jack support and a treadle, whereby the operator is enabled to produce the in-and-o'ut movement of the jack-support on its pivot by an easy natural motion of his foot while his hands are free to jack the boot on the member of the double jack that is not presented to the tool.

The invention also consists in various details of construction of the ,jack and itssupporting and cooperating devices, which will be hereinafter described and claimed.

removingsome of the old partsand substituting those of the present invention.

The devices for supporting the boot or shoe while the heel is presented to the bnrn ishingtool' a comprise a jacksupport b, pivoted upon a bolt 1), secured in a slotted armc of an elbow-lever 0', having pivotproje ctions 0 supported in the usual step d of the Tapley machines, and having-its arm 0 provided with an adj usting-screw c, that bears against the lower part of the upright at, determining the height of the slotted arm 0, which may be raised or lowered by turning the screw 0 in or out.

The distance of the pivotal point of the jack-support b from the upright of the machine maybe varied and adjusted by setting the bolt or pivot 12' in definite positions in the slot of the arm 0, which provides for such ad justment of the support.

The jack-support b is provided at its top with a platform b upon which is pivoted a plate or turn-table 6, provided with a doublejacking device or means for clamping and holding two shoes at opposite sides of the axis The double-jackin g device consists of two heel-seats ff, (see Fig. 3,) which rest against the heel inside the shoe, and corresponding movable heel-plates g g,

supported on arms g operated by screws provided with suitable handles 9 by means of which the heel-plates g 9 may bemoved toward and from the heel-seats f f so as to bear against the top lift or tread of the heel and clamp the same, as shown in Fig.1, or to release the heel and permit the shoe to be withdrawn after the heelis burnished andpermit another shoe to be substituted. The heelseats ff may beheld in fixed relation to the too axis of the turn-table, so as to afford a dellnite limit to the movement of theheel toward the burnishing-tool for the purpose of preventing the tool from passing beyond the heel, and thus damaging the upper of the shoe.

The turn-table e maybe locked with either of the heel-holding devices in line with the axis of the shaft (1. of the burnishing-tool by means of a clutch or locking device consist ing of a dog t, pivoted in a lug upon the sup porting-plate b and provided with a handle t, by which the dog may be moved in and out with relation to the plate, so as to engage and disengage corresponding notches (see Fig. 3) on opposite sides of the turn-table e. A spring 1'' (see Fig. 3) tends to throw the dog into the notch, so that after the heel has been burnished on the member of the jack nearest the tool a, and a shoe has been placed on the opposite jack by the operator during the burnishing operation, the operator has merely to turn the handle 2' and cause the dog to disengage the notch in which it has been resting, and then turn the entire turn-table and donble jack half around,when the dog will enter the other notch and lock the jack with the shoe that has last been placed thereon in position to be operated upon by the burnishingtool.

The general construction of the jack just described enables the operator to remove the burnished shoe and jack another one on the member of the jacking device remote from the tool while the shoe previously jacked on the opposite member is being operated upon by the tool, so that the single burnishing-tool and its actuating appliances perform double duty without loss of time in the operation of jacking the shoes, as the time required for rotating the turn-table is extremely small.

In order that the burnishing operation may be properly performed on a shoe-heel held in one member of the jack without withdrawing the attention of the operator from the operation of jacking a shoe in the other member of the jack, means must be provided for moving the heel that is being burnished in and out with relation to the burnishing-tool that is, toward and from the column or upright a. This may be accomplished by one of the several automatic devices previously invented for this purpose, some of which are shown in patent to Keighley, No. 266,838, dated October 31, 1882, and to Keighley and Blaisdell,

. No. 269,061, dated December 12, 1882, or to Addy, No. 328,371, dated October 13, 1885, any of which devices might be employed in combination with the novel jacking devices hereinbefore described. In accordance with the present invention, however, means are provided by which the operator can produce the requisite movement of the jack by an easy and natural motion of the foot, while his hands are free for jacking the shoe.

The usual yoke-plate lo of the Tapley maohinehas bolted upon it abracket m, to which eeaeee links n are pivotally connected at oneend by bolts n, the other ends of said links being pivotally connected by a belt a with a panof elbowlevers p, pivotally connected by a bolt 7) with the jack-support b and having their free ends connected by a bolt 17 with the rod 0', connected with a treadle or footlever s, pivoted upon a stand t. By this construction and arrangement an up-and-down movement of the rod r, such as produced by rocking the foot resting on the treadle 15, pro duces an inward-and'ontward movement of the joint 1 between the lever 19 and jack-support I), causing the said jack-support to rock on its pivot b and causing the upper part of the said jack and the shoe-support thereon to move inward and outward with relation to the bnrnishing-tool a This inward-and-outward movement may be limited by adjustable stops to a.

It is essential that the heel that is being burnished should rise and fall in its outwardand-inward movement with relation to the bnrnishing-tool in order to so cause the throw of the tool as to cause it to travel fully from one to the other edge of the heetbreast. In the usual Tapley machines this rising-andfalling movement is elfected by a foot-lever or treadle actuated by the foot of the operator, which treadle, however, does not produce the inward-and-outward movement of the heel. The rising-and-falling movement is effected in the present invention by placing the pivot 1), upon which the j tick-support moves, somewhat farther from the upright act the machine than the plane in which the burnishing-tool vibrates, so that as the heel moves out and in on an arc of which the pivot b is the center it has a rising-and-falling movement with relation to the tool or to the axis of the tool-carryingrockshaft or, the amount of which movement may be varied and adjusted by changing or adj usting the position of the pivot b in the slot of its supporting-arm 0, while the actual height of the jack with relation to the tool-shaft may be varied and adjusted by means of the adjusting-screw c of the elbow-lever c, and by means of these two adjustments the position and path of movement of the jack may be properly adjusted for all kinds of heels.

The operation of the present machine is substantially as follows: The operator having jacked the shoe 4; and turned it to the position adjacent to the tool 0. where it is held by the dog or locking device i, causes it to travel under the action of the tool a by means of the foot-lever, and while the heel of the shoe 0 is being thus burnished the operator is engaged in jacking the shoe to. As soon as the heel of the shoe 1; is burnished the operator withdraws the jack from under the operation of the tool by means of the foot-1ever 3, and then turns the handle 7; to unlock the turn-table e and revolves the same until it is engaged by the locking device vlwith the shoe to in position to be burnished, and while the heel of the shoew is being burnished'he it by another one. 7

The construction and arrangement of the removes the shoe 1; from the jack and replaces jack are such that the operator can jack the shoes without changing his position and that the burnished heel can be readilybeaded. V

I claim' v 1. A heel-burnishing machine comprising a burnishing-tool, a jackya jack-, support, a

slotted arm in which the jack-support is pivoted adj ustably in a vertical plane outside of the vertical plane of the burnishing-tool relatively to the standard, and means to rock burnishing-tool, a double jack, a jack-sup port, an elbow-lever pivotally connected to the frame and having a slotted arm to which said support is adj ustably pivoted, and means to rock said support, thereby imparting both the vibrating and rising-and-falling move- 'ment to the jack, substantially as described.

4. A heel-burnishing machine comprising a burnishing-tool, a double jack, a jack-support,- an elbow-lever pivotally connected 7 to the frame and having a slotted arm to which said support is adjustably pivotedg'an adjusting-screw' to vary the elevation of such slottedarm, a treadle, connecting-rod,-and elbow -levers connecting the jacksupport and frame and operable to rock said support and thereby impart boththe vibrating and rising-and-falling movement to the jack, sub stanti'all y as described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses. EVERETT P. RICHARDSON.
